City of Heroes, City of Villains & Going Rogue gaming lessons and gamer training support

The game's first sequel, City of Villains, was launched, allowing players to play as supervillains. Initially dubbed as an "Expanshalone" by the developers (a portmanteau of expansion pack and stand-alone), the game did not require CoH to run, but if the user had both games, content was added to the CoH side of game play. NCSoft merged the two games' subscriptions together, giving users access to both games for a single subscription price.

NCsoft announced their purchase of the CoH/CoV intellectual property and transitioned the staff from Cryptic Studios to a new location in Mountain View, CA to continue development of the game. NCSoft announced to a partnership with Transgaming Technologies to bring both City of Heroes and City of Villains and all 13 expansions to Mac OSX.

City of Heroes: Going Rogue was announced labeled as an expansion, the game centers around the alternate reality of Praetoria and features a new alignment system allowing player characters to shift allegiances between Heroes and Villains, giving characters access to both the Paragon City of CoH and the Rogue Isles of CoV. Paragon Studios describes this as "[exploring] the shades of gray that lie between Heroes and Villains".
